I am not convinced that there is a connection between Risperdal and genital shrinkage. In any case, if there is, then things should return to normal once the drug is discontinued.
I stopped risperdal ago 3 months ago and my penis still remains shrunk, there is a new vein on it. Hyperprolactinmia must be the cause of this? The more I took risperdal the smaller it got and would hurt, it also took away my libido.
Do you think it really will fix itself? There's a few other people its happened to and some evidence that prolactin shrinks penis.
